APPARATUS FOR PREPARING RINGS FOR BALL-BEARINGS- N 0. 841,577. Specification of Letters Patent.

Application filed July 10,1905. Serial No- 269,010.

I is inclined in the direction of the axis of the pin 0, so as to exert a uniform pressure on the ring. A longitudinally-ad ustable lug I: IS connected to the hammer, which lug when Patented Jan. 15, 1907.

To all whom it nut-y concern:

Be it known that I,

, Germany, have a certain new and useful Improvel the hammer is raised actuates one arm of a ment in Apparatus for Preparing Rings for I double lever Z, swinging around a fixed pivot, Ball-Bearings, of which the following is a and sodepresses a rod m. Two collars n on specification. the lower part of the rod produce vibration This invention relates to improvements in of apparatus for lngs; and it consists more particularly in an 1 lower end of the lever p is pivoted a The lever [is also provided with a spring 0, which brings the a double 1 to a rearward] At the he pawl q ratchet-wheel is turned through the distance of one or several teeth. The feeding movement of the ratchet can be regulated by vertical adjustment of the lug Z: or in any other suitable manner. Simultaneously with the movement oi the ratchet-wheel g the conical (Z are set in supporting block, so that each time the hammer rises the ring is fed intermittently-acting devices.

In the accompanying drawings, which illustrate the igure 1 is afront elevation of the improved hammering mechig. 2 is an end elevation, partly in section, on the line A B of Fig. 1. Fig. 3 is a tion carries the ring round by friction carries on a base through a definite amount. At the next op eration the striking-face of the hammer comes against an um 'orked part of the ring, and the operation is repeated.

"1e rings thus preliminarily treated are then subjected to a rolling operation, as described in the specification of my copending application for patent, Serial N 0. 269,011.

Having now described my claim, and desire to secure ent of the United States, is

This block serves to receive a conical pin 0, which has a projection d at-the front and-terminates at the rear in a screw-threaded part c, with an end piece f closing the same. The latter serves to support a ratchet-wheel g, keyed to the pin a. T 1e axis of the pin 0 is perpendicular to the inclined face of the block b, so that it is inby Letters Patcllned somewhat to the horizontal. The cb- 1.
